Sure, but this article is outside of the specifics of Trump - this was just the catalyst for the piece :) As far as I see it, it really isn't going to be necessary to speak any particular language in the near future, because we have tools that can do all the translation on the fly. The idea of "having to learn a language to be productive" will become archaic. It is already a limiting factor that holds back many from being more productive in various communities, and it becomes an unnecessary skill.
Just imagine if a person wasn't able to work, unless they could play the piano adequately. It becomes an unnecessary hurdle.
I get the need for language skill now - but for how long is it a need?
I knew! I digressed. The dude is the president of the country I live in. Did he really say that?
It's different than being able to play the piano. I see folks even more dependent on their electronic devices in your scenario, and that scares the crap out of me. Would we be able to trust the translations? I don't think our being more productive would be a gain for humanity. We are all producing at madcap rates already.
